Not much to say really. It was very basic flight with no entertainment. But it was inexpensive and fine for a short flight. No complaints

Not much to say really. It was very basic flight with no entertainment. But it was inexpensive and fine for a short flight. No complaints

The vietnam airlines app was not able to allow checkin with the confirmation nor with the ticket number. This led to quite a bit of consternation. Speaking with a colleague from Hanoi, he did tell me that their app is not the best. It may be best to inform travelers to only use the link and to plan on checking in at the airport for this airline. The check-in was very easy and the staff were excellent.

flight departure was late, with no updates on status of departure

The aircraft was little tired but the food and service was outstanding

The flight boarded and departed pretty much on time as it’s just a one hour flight there is no food or entertainment so I marked that at the neutral but they do offer water and I’m sure if you needed some food you could bring your own onboard. This was our third internal flight with Vietnam Airways and I recommend them.

The check-in process was great, and I cannot remember the name of the supervisor, but he was good and told us about the transit process very correctly and efficiently and kindly. We were given down access and the overall process was very efficient.

Ensure there is a choice of food for all customers and also enough food

We boarded the plane at 1:20 pm It was hot. There was no air-conditioning It was stifling They kept us on the plane sitting there for 1 hour and 10 minutes

There was no entertainment and food option limited But the service was first class on an economy flight

Technical problems checking in. Had to wait a long time while they got things ready.

Jetstar was terrible. They left us without boarding passes for the connecting flight for several hours, for no reason. They should have given us the boarding passes for the connecting flight, but instead we were stuck in a “customs limbo” in Ho Chi Minh airport until very shortly before we were to board. No reason for them not to give us the connecting boarding passes.

the rudest staff in the world!!! we had overweight baggage, which is our fault but it is a really stupid rule, and the woman said we could reorganise or pay now, we said we’d reorganise and she started shouting “do it now! hurry up!” even though the flight wasn’t even boarding yet. She told us that if our two cabin bags were below 14 together, then we wouldn’t have to pay 500k dong. We reorganised and our bags were below 14kg. She then said that it was all of our bags together that should be less than 14kg. We were obviously confused by this, because she had just said that it was our two cabin bags and we asked her why she told us to rearrange our bags then. She started shouting at us again saying that we needed to “pay now or throw away”. We said fine, we’ll just pay, and she suddenly started asking for 1.51 million dong. I asked her why it was suddenly over three times the price and she said that it was always that price. I asked to see the other piece of paper she had that had the other price and she slammed her one on top of it and started shouting “pay now or i’ll close the gate” (boarding was already finishing at this point). So, we had no choice but to pay three times the original price, even though we reorganised our cabin bags to be under the necessary weight like she had asked us to. I wouldn’t even be so upset about the money if the staff were at least a little bit nice. She was possibly the rudest, most ignorant woman I have ever met in my life. Besides that, the plane/flight was just a bit worse than ryanair standard. Small seats, delayed by an hour. Typical low budget. At least the ryanair staff don’t try to scam you. Avoid at all costs, it’s not worth the hassle of dealing with such horrible people.

Efficient and fast check in, courteous staff at counter and on board. On time departure and arrival. AIR ASIA is my favorite international thailand carrier for reasonable cost and excellent customer service!

Delayed us three times, changed gates twice, and then tried to charge for food on the plane.

Not good in terms of amenities. For over 6 hours they don’t even provide complementary drinks or snacks-forget about dinner or lunch.

Other than the bus wait time to off board passenger when we reached Don Muang, everything else was excellent

Paid for a meal we didn't receive. They admitted they had forgetten ours. No compensation or rectification offered. We requested if they would just give us a glass of wine instead and we would call it even. Crew advised they could not do this and to go to Air Asia counter on arrival and request a refund. Our flight didn't arrive until 2am so this was not a viable option. The crews solution was if we wanted a wine we should purchase one. I was unhappy with that suggestion considering they had already ripped us off with our meal.

We had a 3 hrs delay and they offer McDonalds pineapple pay. They charged us for extra grs of luggage and the experience was not good

No way to talk to support. Is all online self help or chat bot. Now way to speak to a person and the automated options are useless.

Airline cancelled our flight purchased through kiwi.com 2 months before travel and to date has inly refunded half of our paid ticket price.

Crew was nice, boarding efficient. VERY cramped seating. I'm a 5 ' 10'' slim woman and my knees were up against the seat in front of me and my arms were against the arm rests. There are no services, not even water, and they only take local currency and I didn't yet have Thai baht ( flying from Indonesia and no rupiah left). I won't choose to fly with this line again.
